[PATCH v3] git-svn: trim leading and trailing whitespaces in author name

[PATCH v3] git-svn: trim leading and trailing whitespaces in author name

[Tobias Klauser]

In some cases, the svn author names might contain leading or trailing
whitespaces, leading to messages such as:

  Author: user1
   not defined in authors.txt

(the trailing newline leads to the line break). The user "user1" is
defined in authors.txt though, e.g.

  user1 = User <user1@example.com>

Fix this by trimming the author name retreived from svn before using it
in check_author.

v3:
 - check author string length after whitespace trimming
 - trim leading and trailing whitespaces in two separate steps
